What is a deal breaker in your relationship?

Unwarranted accusations. I reckon that goes with unwarranted jealousy.

Doing things in my back and lying about it

Lying, especially about significant things, poor money management (money in, money out mentality), a history of cheating, and (super controversial and triggering on this site) having many partners in the past.

Bodies buried in the back yard, belongs to a cult , sits in the park all night waiting for the ufo to pick her up ?

How’s that

Major lies, cheating, stealing from me or abusing me in any way.

The moment I can't trust her,

The deal breaks apart

A penis

Lying

Being a moocher...

Being financially irresponsible, impulsive/overspending, not taking care of bills. It's been a real issue for me.
